The patch titled
Subject: init/do_mounts.c: add create_dev() failure log
has been removed from the -mm tree. Its filename was
init-do_mounts-add-create_dev-failure-log.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vishnu Pratap Singh <vishnu.ps@xxxxxxxxxxx>
Subject: init/do_mounts.c: add create_dev() failure log
If create_dev() function fails to create the root mount device
(/dev/root), then it goes to panic as root device not found but there is
no printk in this case. So I have added the log in case it fails to
create the root device. It will help in debugging.
[akpm@xxxxxxxxxxxxxxxxxxxx: simplify printk(), use pr_emerg(), display errno]
